NTE1813
Integrated Circuit
Color Signal Processor for VCR
Description:
The NTE1813 is an integrated circuit in a 22–Lead DIP type package. When combined with the
NTE1814, this device provides the functions which process VCR color signals at the 2H/4H/6H mode
is NTSC systems.
Features:
DLow Operating Supply Voltage: VCC = 5V
DLow Power Consumption: 110mW
DAFC and APC System in Recording Mode. APC System Only During Playback Mode.
DBetter S/N Ratio by Chroma ACC (2H/6H Mode).
